IMPROVEMENT IN CARPET-CLEANERS.

Specification forming part of Letters Patent No. 164,773, dated .I une 22, 1875 application filed April 1o, 1875.

To all whom it may concern.:

Be it known .that I, DAVID B. ScoFIELD, of Baker City, in the county of Baker and State of Oregon, have invented a new and useful Improvement in Carpet-Gleaner, of which the following is a specication z Figure l is a longitudinal section ot' my ini-- proved instrument, taken through the line w Fig. 2. Fig. 2 is a cross-section of the same taken through the line y y, Fig. l.

Similar letters of reference indicate corresponding parts.

The object ot' this invention is to furnish an instrument by means of which greasy and dirty spots may be cleaned in a carpet while upon the floor, and so muchot' the suds withdrawn as will enable the wet spot cleaned to readily dry, and which shall be simple in con-V 'in the center of the cap D, placed upon the end of the cylinder or case A. Into the other end of the cylinder A is screwed a ring-cap, E, the opening of which is covered with wire cloth F, to which is loosely stitched a piece of sponge, G. The wire cloth F may be replaced by a piece of cloth, and the sponge G by several plies of cloth loosely stitched together. To the upper part of the tubeA is attached a bracket, H, to serve asa handle for convenience in'handling the instrument, and the upper arm of which enters a notch in the flange ot' the cap D, to prevent said cap from being drawn oft'. In the side ofthe upper end of the tubeA is formed a hole, al, to allow the air to pass out and in freely. In the side of the tube A, toward its lower end, is formed a hole, a2, which is covered with a valve, I, opening outward. The hole a2 and valve I are designed to enable the piston to be worked above said hole and valve without forcing the liquid out of the lower part of the tube A, the

valve being held closed by atmospheric pressure while the piston is being drawn upward, and being opened as the piston is forced downward.

In using the apparatus, a small quantity of very hot soap-suds, to which may be added a small quantity of ammonia, soda, beefs gall, or other ingredients used for removing grease and dirt, is drawn up into the lower part of the tube A. rlhe lower end of .the tube A is then placed upon the carpet over the spot to be cleaned, and the piston is Worked up and down below the -valve I, forcing the suds into and drawing it out ot' the carpet until the grease or dirt has been removed. The piston is then worked above the valve I to draw the suds out of the carpet, the sponge Gr preventing the suds drawn out from llowing out through the lower end ot' the tube, and the valve I preventing it from being Iorced out by the descending piston. In this way the suds can be drawn out so thoroughly that the wet spot will readily dry. The carpet, after being cleaned by the suds, can'be rinsed with clean water in the same way and with the same instrument.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A device for removing spots from carpets, consisting of tube A, provided with the ringcap E, the wire cloth F, and sponge Gr, or their equivalents, the two holes al u2, the valve I, and the piston and piston-rod B O, substantially as herein shownvanddescribed.

Dated this March 28, 1875.
